Hyperuricemia predicts future metabolic syndrome: a 4-year follow-up study of a large screened cohort in Okinawa, Japan

The aim of this study was to determine whether hyperuricemia could predict future metabolic syndrome (MetS) in a large screened cohort of Japanese male and female subjects. We evaluated 5936 subjects (3144 male subjects, 2792 female subjects; mean age 48.7 years) who underwent health checkup programs in 2006 and 2010, who were MetS free in 2006. At baseline, hyperuricemia was detected in 927 male subjects (29.5%) and 276 female subjects (9.9%). Subjects with baseline hyperuricemia had significantly higher MetS prevalence in 2010 than those without (male subjects: 34.8 vs. 20.6%, P
